the water's fine

Here's a pic of SpongeTails and Bigtrick swimming, and they are trying to invite Spongebob and Patrick to go for a swim with them. how ever, they don't seem to want to join. I did this pic before in Photoshop, but when I went to go edit it, it said it was too big and had too many bytes. So i drew it by hand and then ,took it into Photoshop, where inked and colored there.
